Member constants
| value [static] | true if R1::num * R2::den < R2::num * R1::den, or equivalent expression that avoids overflow , false otherwise (public static member constant) |
Member functions
| operator bool | converts the object to bool, returns value (public member function) |
Member types
| Type | Definition |
| value_type | bool |
| type | std::integral_constant<bool, value> |
[edit] Example
#include <iostream> #include <ratio> int main() { if(std::ratio_less<std::ratio<23,37>, std::ratio<57,90>>::value) std::cout << "23/37 < 57/90\n"; }
Output:
23/37 < 57/90
